Abstract

The invention relates to a rainwater collection and utilization device. A rainwater groove is formed in a house; one end of the rainwater groove is connected to a rotary plate by virtue of a torsion rod spring; a water storage groove is hung on the lower part of the rotary plate; when the torsion rod spring is under a natural state, the other end of the rotary plate is attached to an inlet of a sewage pipe; a rainwater collection pipe is arranged below the sewage pipe; when the torsion rod spring is compressed, the other end of the rotary plate can be attached to the rainwater collection pipe; a rainwater storage pond is arranged below the house; the rainwater collection pipe is connected to the inside of the rainwater storage pond; a heat-pump water heater is arranged in the house; a condenser is arranged in the heat-pump water heater; one end of the condenser passes through a compressor, an evaporator and an expansion valve and is connected to the other end of the condenser; the evaporator is arranged in the rainwater storage pond; a heat exchanger is connected to the outlet of a drainage pipe in the house; and the heat exchanger is located in the rainwater storage pond. The rainwater utilization device provided by the invention can supply heat energy in rainwater so as to heat the interior of the house, and the rainwater utilization device is low in energy consumption.

Description

technical field [0001] The invention relates to a rainwater collection and utilization device, which belongs to the technical field of water conservancy equipment. Background technique [0002] According to statistics, nearly 400 of the more than 600 cities in the country are short of water or severely short of water. Especially in some large and super-large cities, the contradiction between supply and demand of water resources is more acute, which directly affects people's life, production and social development. The shortage of water resources has become one of the important factors affecting and restricting the sustainable development of my country's economy and society. With the rapid development of urbanization in my country, greater pressure will be placed on water resources and the water environment. Rainwater utilization is an effective measure to solve the contradiction between water shortage and economic and social development, alleviate the urban water crisis, a...
